Abstract
The utility model relates to a proton exchange membrane for a 200-400 DEG C fuel cell, which comprises a base film with a plurality of pores, wherein proton conduction materials are filled in the pores. Cheap fuels such as hydrogen, hydrocarbons (methane) and methanol (alcohol) can be directly used by the proton exchange membrane, so that the fuel section is varied; and a cheap nickel catalyst can be used by the proton exchange membrane, thus the cost is lowered. At the temperature of 200-400 DEG C, stainless steel can be used as a bipolar plate, thus the problems of corrosion and sealing-in of an acid-base electrolyte or fused salt electrolyte of a low-temperature fuel cell are avoided, the problem of corrosion resistance to the bipolar plate is solved, the condition that a high-temperature solid oxide must use high-temperature resistant ceramic is avoided, therefore, the cost is lowered. Finally, an inorganic solid electrolyte is used as the proton conduction material, thus the problem of degradation of the traditional polymer as the proton conduction material can be overcome, and the service life of the fuel cell is greatly prolonged.

Technical field
The utility model relates to a kind of amberplex, particularly relates to the PEM of a kind of 200-400 of being used for ℃ fuel cell.
Background technology
Fuel cell (FuelCell) is the TRT that a kind of chemical energy that will be present in fuel and the oxidant is converted into electric energy; Have generating efficiency height, advantage such as low in the pollution of the environment; Its with the performance of excellence and to environment characteristics such as pollution seldom be known as the 4th generation generation technology; All drop into the commercial applications that huge fund is come the exploration and practice fuel cell with the national governments headed by the America and Europe, each big motor corporation and research institution since the nearly more than ten years, started the business-like research and development upsurge of fuel cell.
The development of whole world fuel cell has been absorbed in predicament at present.From the present state of the art and the problem of existence, generally believe that life-span and cost are its business-like bottlenecks of puzzlement, and problem of materials is the key problem of fuel battery service life and cost.Have only the change of material being carried out essence, just may bring increasing substantially of fuel battery service life.In addition, cost also is one of business-like bottleneck of restriction fuel cell.
Yet fuel cell of the prior art, therefore, is not suitable for and can replaces hydrogen with other cheap fuel because the hydrogen storage problem also is not resolved at present with the low problem of the working temperature of plyability anion-exchange membrane; In addition, under the temperature the end of than, must use platinum to make catalyst, therefore, cost is higher; Further, there be the corrosion and the sealing-in problem of soda acid electrolyte or molten salt electrolyte in low-temperature fuel cell.
The utility model content
The purpose of the utility model provides a kind of Raney nickel that can directly use cheap fuel such as hydrogen, hydro carbons (methane), first (second) alcohol, available cheapness, can use stainless steel to do bipolar plates, can improve the PEM that is used for 200-400 ℃ of fuel cell of fuel battery service life.
For solving the problems of the technologies described above, the utility model is taked following technical scheme: the PEM of a kind of 200-400 of being used for ℃ fuel cell is characterized in that: comprise the basement membrane with a plurality of holes, in said hole, be filled with proton-conducting material.
Further, the porosity of said basement membrane is greater than 70%.
Further, said basement membrane is poly tetrafluoroethylene or polyimide film.
Therefore PEM in the utility model, can directly use cheap fuel such as hydrogen, hydro carbons (methane), first (second) alcohol owing to be operated in 200-400 ℃, makes fuel select diversity; The Raney nickel of available cheapness also, thus cost reduced; Under this temperature; Can use stainless steel to do bipolar plates; Thereby avoided the corrosion and the sealing-in problem of the soda acid electrolyte or the molten salt electrolyte of low-temperature fuel cell, both solved problem, must use resistant to elevated temperatures pottery unlike high-temperature solid oxide is such again simultaneously the corrosion resistance of bipolar plates; Therefore, further reduced cost; At last, inoganic solids thing electrolyte is that proton-conducting material can overcome the degradation problem that present polymer is a proton-conducting material, and the life-span of fuel cell is increased substantially.
Description of drawings
Fig. 1 is the structural representation of the PEM that is used for 200-400 ℃ of fuel cell in the utility model.
Embodiment
Be elaborated below in conjunction with the technical scheme of accompanying drawing to the utility model.
As shown in Figure 1, the PEM of the said 200-400 of being used for ℃ fuel cell comprises the basement membrane 1 with a plurality of holes 2, in said hole 2, is filled with the proton-conducting material that is made of the inoganic solids thing electrolyte that contains zirconium and silicon.Because it is present with the degradation problem of polymer as proton-conducting material that employing inoganic solids thing electrolyte as proton-conducting material, therefore can overcome, and the life-span of fuel cell is increased substantially.
Preferably, the porosity of said basement membrane 1 is greater than 70%, and further, preferably, said porosity is 80%.
Preferably, said basement membrane 1 is poly tetrafluoroethylene or polyimide film.
Further specify the manufacturing process of the PEM in the utility model below through an embodiment.
